Question

a telemarketers computer selects phone numbers at random.the telemarketer has recorded the number of respondents and each age bracket for one evening in the following table .what is the probability that the next responded will be 25 or younger? enter a fraction or round your answer to four decimal places if necessary Under 18=2418-25=2326-35=4036-45=58over 45=50

Answer 1

SOLUTION:

The probability that the next responded will be 25 or younger is ;

$P(x<25)=\frac{total\text{ }under\text{ }25}{total\text{ }number\text{ }of\text{ }respondents}$

Thus, we have the probability to be;

$P(x\leq25)=\frac{24+23}{24+23+40+58+50}=\frac{47}{198}=0.2374$

Thus, the final answer is 0.2374
